Question

嗨我有2个下拉列表：

 <?= $form->field($model, 'Rel_User')->widget(Select2::classname(), [
    'data' => ArrayHelper::map(UrUser::find()->orderby('Surname')->all(), 'Id', 'fullName'),
    'language' => 'pl',
    'options' => ['placeholder' => Yii::t('app', 'Wybierz użytkownika ...')],
    'pluginOptions' => [
        'allowClear' => true
    ],
]); ?>

    <?= $form->field($model, 'Rel_Category')->widget(Select2::classname(), [
    'data' => ArrayHelper::map(SmUserCategory::find()->orderby('Name')->all(), 'Id', 'Name'),
    'language' => 'pl',
    'options' => ['placeholder' => Yii::t('app', 'Wybierz kategorię ...')],
    'pluginOptions' => [
        'allowClear' => true
    ],
]); ?>

如果没有选择第二个，我想要其中一个是必需的。因此，如果用户不选择它们，则应在其中两个下显示消息，但如果用户选择一个，则应保存我的模型。我尝试用规则做到这一点：

 [['Rel_User'], 'required', 'whenClient' => "function (attribute, value) {return $('#banner-rel_category input[type=dropdown]:checked').val() == null}"],
 [['Rel_Category'], 'required', 'whenClient' => "function (attribute, value) {return $('#banner-rel_user input[type=dropdown]:checked').val() == null}"],

但现在需要2个时间。我能做些什么呢？我的动作是在ctrl中创建的

 public function actionCreate() {
            $model = new Banner();
            $model->scenario='create';
            if ($model->load(Yii::$app->request->post())) {
                $model->File = UploadedFile::getInstance($model, 'File');
                if ($model->save() && $model->upload() && $model->validate()) {
                    return $this->redirect(['view', 'id' => $model->Id]);
                }
            } else {
                return $this->render('create', [
                            'model' => $model,
                ]);
            }
        }

我现在的规则：

public function rules() {
        return [
            [['Url'], 'required'],
            [['File'], 'required', 'on' => 'create'],
            [['Rel_User'], 'my_required'],
            [['Rel_Category'], 'my_required'],
            [['Views', 'Rel_User', 'Rel_Category', 'CreatedAt', 'UpdatedAt', 'IsDeleted', 'Id'], 'integer'],
            [['Image', 'Url', 'Caption'], 'string', 'max' => 255],
            [['Url'], 'match', 'pattern' => '/^(http(s?):\/\/)?(www\.)?[a-zA-Z0-9\.\-\_]+(\.[a-zA-Z]{2,3})+(\/[a-zA-Z0-9\_\-\s\.\/\?\%\#\&\=]*)?$/'],
            [['File'], 'file', 'extensions' => ['gif', 'jpg', 'png', 'jpeg', 'JPG', 'JPEG', 'PNG', 'GIF'], 'checkExtensionByMimeType' => false,],
            [['CreatedAt', 'IsDeleted'], 'safe']
        ];
    }

Answer 1

在模型中使用自定义验证：

public function rules()
{
  return [      
     [['Rel_User, Rel_Category'], 'my_required'],
  ];
}

public function my_required($attribute_name, $params)
{
   if (empty($this->Rel_User) && empty($this->Rel_Category)) 
   {
     $this->addError($attribute_name, Yii::t('app', 'At least 1 of the field must be filled up properly'));

    return false;
   }

   return true;
}
